CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No.320,4l2, dated June 16, 1885.

Application filed April 29, 1885. (No model.)

.To all whom, it may concern:

Be it known that I, EDWARD B. STRONG, of Detroit, in the county of Vayne and State of Michigan, have invented new and useful improvements in Lubricating Oar-Axles; and I do hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, which form a part o'f this specification.

This invention relates to certain new and useful improvementsinthe means and method of lubricating railroad-car journals within their boxes by the employment of capillary attraction.

The novelty consists in the peculiar combinations and the construction and arrangement of parts hereinafter more fully described and claimed.

Figure l is a vertical cross-section of acaraxle box, showing the axle journaled within the box, the brass bearing above the journal, and the wedge interposed between the top of the brass bearing and the top of the box. Fig. 2 is a longitudinal vertical central section of the same.

In the drawings, A represents the box, which is of any ofthe known or approved forms of construction. B is the ljournal of the caraxle within said box. C is the brass bearing, saddled upon the topoi the ljournal-bearing; and D is the wedge interposed between the top of said brass bearing and the top of the box. E are wicks, preferably formed each in one length, suiiicient to rea-ch far enough below the axis of the car-axle to meet the oil found in the well of the axle-box, as shown in both figures, although it will not be necessary for the ends of such wicks to extend clear to the bottom of the well, as there shown, as such well Inay be filled with waste saturated with oil, when it would only be necessary for the ends of the wick to extend far enough down'- ward into such waste as to attract and take up the oil.

ln the drawings presented, channels a are cut or formed laterally across the top of the brass bearing, and the wicks lie in these channels. Oriiices or perforations b, are formed in and through the brass beariugs,af fording the only means of communication through which the oil carried up by the wicks can nd its way to the top of the journal of the car-axle, the rapid revolution of which has a tendency to create a Vacuum in these passages b, which causes the oil carried up by the wicks to be frequently discharged through such passages.

It will be noticed that in the drawings the top surface of the brass bearing is convex from end to end, the highest point being in the longitudinal center of such bearing.- It will also be noticed that the wedge is perfectly dat, with its top and bottom sides parallel, so that when the box and journal stand level (as when not in operation) the Weight imposed is directly Aupon the center of the brass bearing; but when these parts are in use-for instance, as under a carin motion-the box will rock slightly upon the top of the brass, and at each oscillation the tendency will be to squeeze or press the oil in the wicks alternately and force such oil more freely to flow through the passages leading through the brass bearing. WVhere this form of application is shown, recesses c are formed across the lower face of the wedge coincident with the recess formed in the top of the brass bearing to receive the wick. It is not essential, however, that the construction -and application herein shown should be at all times used in order to produce a perfect oiling of the journal by capillary attraction, as the same result would be produced were the wick to be carried up and across the top of the wedge and interposed between thc top of such wedge and the top of the box, so long as coincident perforations through the wedge and the brass bearing` would permit the oil to be discharged onto the journal.

that I claim as my invention is- 1. The combination, with a channeled brass bearing, and with lubricating-wicks arranged upon either side of an oval center thereof, of a rocking block adapted to compress the wicks alternately, as' and for the purposes set forth.

2. In a car-axlebox, and in combination therewith and with a car-axle journal, a brass bearing having one or morelateral channels formed in its upper face, communicating with passages leading downward through such bearing, and a wedge between such bearing and the top of the box, the parts being constructed IOO and operated substantially as and for the purpor es set forth.

3. ln a ear-axle box, the bearing-brass C,

upon the oval center of the brass7 as and for the purpose' specied.

j having transverse channels a, arranged upon EDWD B' SThONG 5 either side of an oval center, and having per- Witnesses:

forations b, combined with the Wicks E and H. SPRAGUE, the Wege D, having recesses c, and resting UHARLEs J. HUNT.
